Opera announced a beta app called Opera Max, that aims to save on data usage of Android devices. The Opera Max app compresses the data including images, photos and videos to save your limited plan data. Opera Max does this through forming a VPN around the connection, it will tunnel all the data flowing through your Android device to Opera’s servers for compressing.
Opera says they will only measure how much data you are using and how much your are saving. Opera Max works for browser data as well as app data, as it forms a VPN. There is one catch though, it can’t save on encrypted data, all un-encrypted traffic will the get the data savings. This is not a problem because only few app like Facebook use complete encryption.

Opera says the data you can save using this app depends on your data usage, that is true because it all depends on how much savings you get after compressing the content and it varies with the content and the source.

We only provide savings for HTTP non-encrypted data usage. Opera Max will not save you data on applications that use HTTPS encrypted or other protocols, like User Datagram Protocol. In normal English this means that you won’t save data on encrypted apps, which includes some top apps like Facebook, but you will save data on the majority of apps and any content that is not encrypted.

The Opera Max is currently in closed beta testing and Opera is inviting users from US to come forward to take part in the beta testing program. Here is what you have to do to participate in the closed beta testing of Opera Max.
